    摘要： The invention is directed, in an embodiment, to a method for producing a transgenic plant comprising: providing a substantially homozygous plant line suitable for transformation; selecting a subline of the plant line having reduced heterogeneity; transforming plant materials from the subline with a transgenic construct that confers a desired trait to at least one transformed plant; recovering at least one transgenic event from the transformation step; and selecting a transgenic event exhibiting a desirable level of the desired trait using plants of the subline as control. The invention is also directed to a method for producing a plant having a desired trait comprising: providing a substantially homozygous plant line; selecting a subline of the plant line having reduced heterogeneity; crossing at least one individual of the selected subline with a donor parent having at least one desired trait to form at least one second individual having the desired trait; and backcrossing the at least one second individual with the at least one individual of the selected subline as a recurrent parent to form at least one progeny plant having the desired trait.
